SixcutterFreq
This is a little Hypercard stack I wrote a couple of years ago. I thought it
was too trivial to upload, but I use it myself every once in a while,
so I thought "What the heck!". The stack calculates the frequency of the various
six-cutter restriction enzymes in a few different genomes. The algorithm is
based on the frequency of dinucleotide pairs, i.e., nearest-neighbor frequency.
Unfortunately, nearest-neighbor analysis has been performed on only a few
species, and they're the one's analyzed in this stack. If you look at this
stack, and you're aware of nearest-neighbor data for any other species please
tell me! DNA's with available nearest-neighbor data : bacteriophage lambda,
Mus musculus, wheat, Brassica, E. coli, Chlamydomonas, Saccharomyces,
Gallus, Homo sapiens.
